"Cute little lightning dragons?" Krune muttered with a hint of confusion. "Them?"

And as if right on cue, a gigantic lightning dragon slammed into him, eliciting screams from him as he condensed a layer of ice to defend himself. The ice layer was broken immediately as the lightning behaved like it was sentient, retracting its body a little before slashing its claws at Krune, ripping apart his barrier.

It then coiled around him, emanating countless lightning bolts that slammed into him nonstop, beginning to char his skin. Whenever he erected a barrier around him, its claws would attack it, destroying them.

Little Cally's laughter echoed every time this happened, stating after some time had passed, "Oh, I'm not aiming for you, Sterlena. You're just coincidentally around Krune. So yeah you know just enjoy them, I guess?"

"Who the hell can enjoy them?" Sterlena retorted in response as a second lightning dragon arrived and slammed into her. She erected countless barriers around her, defending herself, from time to time also helping Krune.

"Way to go, big sis. You've made it way worse than it originally would have been," Krune muttered as he was slapped by a lightning dragon, flinching from the attack before punching it in reverse by condensing a massive fist of ice.

Of course, the ice shattered instantly when a bolt of lightning slammed into it.

"Yes, it may be dangerous. But the benefits are higher as well," Sterlena said, transmitting her voice to him through Divine Sense. "Didn't you obtain the Tribulation Lightning Law? Use one of your clones to unleash your Spiritual Mark on a Blank Law Core and begin comprehending the law again."

"But I've already comprehended it to the God Trial Realm. The Blank Law Cores that are left can only raise my comprehension to the Semi-God Realm. They wouldn't work for my Tribulation Lightning Law anymore."

"Trust me, it'll work," Sterlena shouted in response, "All you need to achieve is the process of you being able to comprehend the Law of Tribulation Lightning. That way, you'll actually be able to bypass the natural restriction and gleam into the truth of the heavens. That's why I made the both of us breakthrough at the same time!"

Krune's eyes lit up as both he and Sterlena returned to their demon beast forms, looking no different from one another.

"Another wisp? In the God Realm?" Feifei was shocked. "Shouldn't Krune be the only one here at present?"

The Wisps should have increased in number within the Godly Path Realm by now. But for the God Realm, that shouldn't have been the case. Even if they arrived here, they shouldn't have accumulated enough to attempt a breakthrough to the Semi-God Realm.

Also, based on what she sensed, Sterlena was strong, too strong for a Nascent God. So, it made no sense.

"Who is she?" Feifei wondered, especially since Krune's breakthrough had begun the moment she came out. So, she didn't have much time to interact with him.

Boom!

Followed by a mighty roar, a lightning dragon slammed into Krune, causing him to endure the pain while within his subspace, all the Little Krune Fragments joined together to turn into a whole once again, after almost a century.

Little Krune used all his power to activate his Spiritual Mark, slamming a powerful bolt of tribulation lightning into a Semi-God Realm Blank Law Core, turning it into a Tribulation Lightning Law Core.

As he began to absorb it, Krune's eyes lit up as he suddenly sensed that he was able to probe into the lightning dragon. The headache that he felt when trying to sense the Tribulation Lightning Law was no longer there, allowing him to forget the pain from the attacks and focus slowly on comprehending it.

Moreover, thanks to Sterlena's intervention, the tribulation lightning had advanced to a higher form now. Not only was it dangerous and life-threatening, but the concentration of the Tribulation Lightning Law was also dozens of times more than before.

As his Divine Sense was on the level of a God Trial Realm cultivator, the moment he activated it, he was lost in a sea of thought, comprehending the essence of the Tribulation Lightning Law. His Mental Energy broiled, causing a sea of it to churn, allowing him to process his thoughts faster.

Thanks to Little Krune comprehending the Tribulation Lightning Law Core, he was able to understand it better and better. However, this also meant he was unable to defend himself under the tribulation.

Fortunately for him, Sterlena chimed in, shielding him to the best of her ability. Even though they were having a hard time, thanks to Krune's tough physique, even if some lightning bolts slammed into him, he wouldn't die.

On top of that, the healing effect of his Ocean Heart would begin to heal him. As he had returned to his wisp form, his Soul Needle peeked out from his core, causing countless lightning bolts to be pulled towards it as if it was a lightning rod.

Krune's Spiritual Mark shone from the depths of his soul, unleashing sparks from time to time that interacted with the tribulation lightning, amplifying themselves.

"This is the best tempering one can find." After some time had passed, Sterlena closed her eyes, letting go of all defensive means as she took on all the hits, being injured severely.

Then, she riled up her Spiritual Incarnation, using the tribulation lightning to temper her various laws, to an extent surpassing her previous level.

Her Spiritual Incarnation not only grew tougher, but the alignment, interaction, and cohesiveness of the various laws forming them increased. Instantly, it felt like her mind was released from the confines of her body as her consciousness spread throughout her Divine Sense.

For a moment, her body of a True Spirit exploded into a sea of flames, ethereal in nature, unaffecting even Krune as it spread around, absorbing the countless lightning bolts that slammed into them.

Suddenly, the lightning dragons writhed in pain for some reason as all the power in them was voraciously sucked in by her. Once it was done, the sea of flames condensed back, forming her body as a True Spirit, hovering with no aura whatsoever.

Similarly, Krune's Wisp body also did the same, but instead of a sea of flames, it just vanished, conceptualizing into Divine Sense instead.

The lightning dragons attacking him turned still immediately as the form of sentience they displayed was sucked out from them and absorbed by Krune, turning them into regular lighting bolts.

His body condensed into the wisp form after that as the lightning clouds slowly dispersed. And slowly, the aura of a Semi-God Realm cultivator was emitted by both Krune and Sterlena.

Breakthrough complete!
